Nothing really, but 6th gen doesn't exist yet. I THINK the 5.5 gen are a little less thick. But other then that I don't know of any huge difference.
hi they sell 6th generation on ebay?its just i dont want to buy 5th or 5.5 generation when the 6th generation is better..
I'm pretty sure that 6th generation isn't out yet, and the ones you see on ebay are just false posts or people that don't know what generation their iPod is. The 5.5 is the one you will find in stores, so that will be the easiest one to get. As I said above, there is really not that much different.
